摘要： There is provided a pulse detecting device which resists fluctuations in the quality by locating an ultrasound transmitting piezoelectric element and an ultrasound receiving piezoelectric element with high precision. In the pulse detecting device, a detection sensitivity of the pulse is improved. A transmitting piezoelectric element and a receiving piezoelectric element are fixed onto a substrate by electrodes. The transmitting piezoelectric element is excited in response to an inputted drive voltage signal to generate an ultrasound and transmits the generated ultrasound to a living body. The receiving piezoelectric element receives an echo produced by reflecting the ultrasound transmitted into the living body by a blood flow of the living body and converts it into a voltage signal. A processing arithmetic unit compares the frequency of the ultrasound generated by the transmitting piezoelectric element with that of the echo received in the receiving piezoelectric element to thereby detect a pulse.

摘要： In a pulse wave detecting device for detecting a pulse wave by use of an ultrasonic wave, in order to prevent attenuation of the ultrasonic wave caused by a gap formed between the pulse wave detecting device and the user's skin, a transmitter for generating an ultrasonic wave and a receiver are formed on a support substrate so as to protrude therefrom. Consequently, the transmitter and receiver contact a surface of the skin and no gap is formed between the surface of the skin and the pulse wave detecting device. A pulse wave detecting device high in detection accuracy is thus realized without the need for applying a gel between the skin and a detecting surface of the device.

An information processing portion calculates an intensity at each of frequency components of the Doppler shift signal, extracts a maximum frequency in a signal at an intensity level equal to or larger than a threshold in the histogram or a maximum frequency when an integrated value from a low frequency component reaches a predetermined rate of a total thereof in the histogram, and provides a temporal change waveform of the extracted frequency. The blood rheology is analyzed based on the maximum frequency in the frequency waveform.
